1Cut the sweet onions into thick slices, being careful not to make them too thin.
2Mince the garlic cloves.
3Heat olive oil and ghee in a large pot over the stove.
4Add the sliced onions to the pot and sprinkle with salt to draw out moisture.
5Sauté the onions, starting on high heat, then reducing the heat once color develops, and caramelize until deep, rich, and golden brown.
6Stir in the minced garlic and fresh thyme until translucent.
7Add the bay leaves and deglaze the bottom of the pot with bourbon whiskey.
8Pour in the chicken stock and beef stock, season with black pepper, bring to a boil, then reduce the heat and simmer.
9Stir in the sherry vinegar.
10Ladle the soup into oven-safe bowls, top with toasted baguette slices and a generous amount of grated Gruyère, and broil until the cheese is melted and browned.
